How King Heating, Cooling & Plumbing Recovered $7,000 in One Week with 3rd Armor

When you’re processing thousands of supplier invoices every month, it’s easy for overcharges and errors to slip through unnoticed. For King Heating, Cooling & Plumbing—a trusted service provider since 1968—this was an everyday risk that left margins exposed.

The Challenge: Hidden Errors in Thousands of Invoices

King Heating, Cooling & Plumbing was managing 2,000–3,000 supplier invoices monthly. Without the time or visibility to validate each one, invoices were simply approved and paid. Leadership suspected overbilling but lacked the resources to confirm or recover those dollars.

The Solution: Concierge Invoice Monitoring

That’s where 3rd Armor stepped in. Our concierge invoice monitoring service flagged $7,000 in errors on water heater invoices in just the first week—errors the team never would have found on their own. From that point forward, every invoice was audited before payment, giving King Heating, Cooling & Plumbing complete confidence in supplier billing accuracy.

And the best part? Their staff didn’t have to lift a finger. 3rd Armor handled the process end to end, ensuring every invoice was reviewed, every error addressed, and every dollar protected.

The Results: Immediate ROI and Lasting Confidence

• $7,000 recovered in one week

• Peace of mind with full invoice visibility

As Joe Clark, General Manager at King HVAC Systems, shared:“3rd Armor uncovered overcharges we never would have found on our own. The savings paid for the service immediately—and now every invoice is validated with confidence.”
